It turns out the duo have unfollowed each other on Instagram, and it's being reported that there's a really shady reason why!

The Dirty is saying the songstress allegedly hired a convicted felon to "troll" her husband Eddie Cibrian's ex-wife by harassing and stalking her. Uhh, what??

It's obviously hard to say how true these out-there allegations are, but according to Bullyville.com's James McGibney, there's some seriously shady stuff going on:

"Brandon King is a convicted felon who was hired by the Spina Law Firm out of New Jersey. We heard through some back channels that the Spina law firm hired Brandon to troll celebrities online. Until I got my hands on that transcript, it was pretty hard to prove that he worked for them… This guy is the worst of the worst. (An) alleged child abuser, alleged woman abuser, alleged convicted felon, etc……why on earth would Leann Rimes hire someone like this?"

The Dirty also provided a transcript of the court documents confirming Brandon does work for the Spina Law Firm, though the document explicitly has him stating:

"I have a contract with Leanna Rhimes, too."

Yes, the spelling is off, so who knows what's actually going on there.

But earlier in the document, Brandon confirms his previous work trolling celebs:

"I used to do something that was — I would identify what they would call 'troll accounts' for celebrities, and I'm just real good at it. So that's how it initially started. And then it spread mouth of word — word of mouth through that and people started contacting me asking me for help. And then a law firm approached me and said, hey, are you interested in creating a business out of this. And I said, well, yeah, sure. And then so they went headlong into creating a business for me out of it."

He also names Joanna Krupa as a client, which is interesting because she's also known to be feuding with Brandi.

If all of this true, then this is just crazy!!

We'll let you know if there are any updates of if either of these ladies speak out!
